Depending how badly floodwaters churned up river bottoms, many salmon eggs could have been unearthed from their hiding place, swept into the water column and died.
Salmon spotted "swimming" across the road as days of heavy rain
results in flooding along the Skokomish River in western Washington

As Washington state’s salmon remain poised on “the brink of
extinction,” this year’s severe flooding could prove to be a wild

several more later that night while ferrying friends across the
property in a canoe.
Morse is just one of thousands of people across western Washington
and British Columbia who experienced severe flooding in
mid-November. A potent atmospheric river storm — a long, narrow
corridor of tropical water vapor that, when forced upward by

between Nov. 14 and 15 than it usually does in the entire month.
Rivers like the Skagit and Nooksack spilled over their banks, and
salmon, like the ones Morse saw on his driveway, were washed out of
